When compiling Python C-API extensions with "-Wextra", warnings like warning: unused parameter ‘self’ [-Wunused-parameter] appear for code (like below). It seems like a minor issue for a warning to appear when "PyObject *self, PyObject *args" is required. Is there an underlying issue in the API? static PyObject *mathfunc_ismersenneprime(PyObject *self, PyObject *args) { sllint num; ASSERT_LONGLONG_ARG(num); if (num < (sllint)0) ERR_POSITIVE_INT; returnbool(islonglongmersenneprime(num)); }

> Is there an underlying issue in the API? You can use self if your code. If you don't need it, you can use Py_UNUSED() macro available since Python 3.4.
